Infernal Cape is a requirement for any player striving for RuneScape greatness. To be rewarded the Infernal Cape a player must complete the Inferno minigame. To begin the minigame, you must first acquire a simple Fire cape, which is a lower-tier version of the Infernal cape, and give it to TzHaar-Ket-Keh. Infernal cape provides the best stats for melee-oriented characters and only a couple of other items can be used against it and that's for only on very distinct conditions.
